Abstract
Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.
Claims18
An implantable stent comprising:
- a tubular member formed of a plurality of interwoven wire filaments, the tubular member having a longitudinal length extending from a first end of the tubular member to a second end of the tubular member;
- wherein the tubular member has a circumferential outer surface, a circumferential inner surface, and a central longitudinal axis extending through the tubular member;
- wherein the tubular member includes a plurality of longitudinal channels extending parallel to the central longitudinal axis, the plurality of longitudinal channels each extending only partially along the longitudinal length of the tubular member;
- wherein the plurality of interwoven wire filaments are displaced radially inward from the circumferential outer surface to form the plurality of longitudinal channels.

An implantable stent comprising:
- a braided tubular member having a first end and a second end, the braided tubular member including:
- a generally cylindrical body having a central longitudinal axis, a circumferential outer surface and a circumferential inner surface, the generally cylindrical body having a longitudinal length extending from the first end to the second end of the braided tubular member;
- wherein the braided tubular member is formed of a plurality of braided wire filaments extending from the first end of the cylindrical body to the second end of the cylindrical body;
- wherein the generally cylindrical body includes a plurality of longitudinal channels extending parallel to the central longitudinal axis and spaced circumferentially around the generally cylindrical body, the plurality of longitudinal channels formed by displacing the plurality of braided wire filaments radially inward from the circumferential outer surface;
- wherein each of the plurality of longitudinal channels extends only partially along the longitudinal length of the braided tubular member;
- and
- a covering disposed about the braided tubular member.

- wherein each of the plurality of longitudinal channels extends only partially along the longitudinal length of the braided tubular member;
- and
- a covering disposed about the braided tubular member;
- wherein the braided tubular member includes a flared end region flared radially outward from the generally cylindrical body at the first end of the braided tubular member, wherein each of the plurality of longitudinal channels extends only partially along the generally cylindrical body but does not extend along the flared end region.
